I live on the first floor, and installing an elevator severely blocks light and makes noise. I only agree to install a corridor elevator. The uncle and aunt upstairs agreed wholeheartedly, but secretly installed an ordinary elevator while I was on a business trip and even kidnapped me morally. I was so angry that I turned my house into a columbarium and filled it with urns. They made trouble and went to the media to no avail. In the end they had no choice but to buy my first floor at a high price and suffer the consequences.
